Fabric impregnated with TiO2 gel with self‐cleaning property

Abstract

AbstractCotton fabric decorated with TiO2 synthesized by sol‐gel approach was investigated as a self‐cleaning material depending on the TiO2 loading (1.5 wt% in the case of single layered fabric and 3 wt% in the case of double layered). The materials were investigated by SEM, EDX, XRD, FTIR, and photoactivity. The self‐cleaning property was established by determining the amount of the coated dust, the elemental composition, the carbon content, the opacity, and the water contact angle. The self‐cleaning property of the impregnated fabric was accentuated by TiO2 loading. The dust deposited on the single layer fabric stored inside was 3.8 wt% lower than on the nonimpregnated fabric and that deposited on double layer fabric, respectively, was reduced by 9.1 wt%. The decrease in the deposited dust was more accentuated for the samples stored outside (4.2 wt% for the single layer fabric and 16 wt% for the double layer fabric, as compared with the nonimpregnated textile).
